Abstracts ASN Report 2019

ASN observes that most EITs are reported by nuclear industry players, with few reports from players in the medical and non- nuclear industry sectors when one considers the transport traffic concerned. ASN does however point out that notification of EITs is not a regulatory obligation. Ł ӅӃӄӌё ĹłňŅ ņļĺŁļĹļĶĴŁŇ ĸʼnĸŁŇņ ŅĴŇĸķ ĿĸʼnĸĿ ӄׇłŁ ŇĻĸ ņĶĴĿĸ were reported to ASN.

These events had no actual consequences for safety or radiation protection. However, in the event of an accident, a non-conformity can impair the robustness of the package; ҄ stowage errors concerning contaminated equipment and tools transported in containers and deformation of these containers; ҄ the shipment of packages containing radioactive substances by unauthorised conveyance, as well as delivery errors or packages being temporarily mislaid; ҄ the presence of contamination spots exceeding the regulatory limits, detected on drums containing natural uranium ore transported in containers, in containers transporting contaminated equipment and tools, on conveyances which have been used to transport spent fuel packages. With regard to radiation protection, the impact of these events is low because the contamination spots detected were inaccessible. 0ɮƺȇɎɀ ȸƺǼƏɎƺƳ ɎȒ Ɏǝƺ ɎȸƏȇɀȵȒȸɎ Ȓǔ Ȓȸƺ ǔȸȒȅ ɎǝǣȸƳ ٮ ȵƏȸɎɵ ƬȒɖȇɎȸǣƺɀ Recurring deviations have been observed in fuel cycle natural uranium ore transports from mines in Central Asia, Africa and Australia: on their arrival in France, contamination spots exceeding the regulation limits and damaged drums are discovered.
